Document Type and Number:
WIPO Patent Application WO/2022/121292
Kind Code:
A1
Abstract:
A washing machine, wherein a suspension (32) for supporting an outer drum (21) of the washing machine in a tub (1) comprises: a free piston (325) which can freely slide relative to a damping cylinder (321); a pair of fixed pistons (323a, 323b) which have a separation distance (L1) covering the play of the free piston (325) and are fixed to a rod (322); and an upper elastic body (326a) and a lower elastic body (326b) which are arranged between the free piston (325) and the fixed pistons (323a, 323b). The elastic coefficient (ka) of the upper elastic body (326a) and the elastic coefficient (kb) of the lower elastic body (326b) are respectively defined such that the deformation thresholds (ΔDa, ΔDb) are higher than the allowable deformation thresholds (ΔDa(T), ΔDb(T)) corresponding to a defined noise threshold (T).
